“…This means that the rabbit and deer are lesser suitable for R. annulatus feeding than cow and rabbit is greatly lesser suitable than both deer and cow. In this study, pre-oviposition period for R. annulatus female fed on rabbit was 3 days in agreement with the period recorded by Jagannath et al (1982), Ouhelli et al (1982) and Davey (1988). Oviposition period for female fed on rabbit was 7 days lesser than that for female (19.2 days) fed on cow that recorded by Davey et al (1980).…”

The cattle tick Say, 1821 (Acari: Ixodidae) is the main tick species on cattle in Egypt. This study was designed to know the possibility of rearing on rabbits in order to obtaining an adequate tick number and maintaining this tick species in lab to the next generation. Additionally, a comparison was performed between some biological parameters in fed on rabbits with that fed on cows. Six New Zealand white rabbits were used as a lab animal for rearing. The animals were divided into two groups. The first (G1) included four rabbits and the second (G2) included two rabbits. In G1, larvae fed until to reach unfed adults those were detached, cleaned their mouth parts carefully and re-fed on another rabbit. In G2, larvae were maintained on rabbits until to the fully fed females dropped. Oviposion, hatchability and life cycle of fed on rabbits were recorded and compared with those fed on cows. Results showed that although the cattle tick is highly specific to cattle, it is possible reared on rabbit in limited scale. The larvae well developed on the same rabbit to nymphs and adults. In G2, a very few adults completed their feeding and laid very small egg mass, some of eggs failed to hatch and a few recorded hatchability percentage not more than 9.1% in comparing 98.3% in females fed on cow. In G1, the rearing technique led to slightly increase the egg mass and their hatchability that reached to 23.6% in comparing with the hatchability recorded in G2.

“…Further, the ticks have ability to protect themselves against adverse climatic conditions and enter diapause, leading to delayed morphogenesis and reduced behavioural activities and they pass winters as engorged females, nymphs, larvae and unfed adults by hiding into the cracks and crevices in the walls (Gray 1991;Urquhart et al 2003). It has also been suggested that female B. microplus has capabilities of converting its body weight to egg mass until the temperatures reaches a critical upper limit (Ouhelli et al 1982;Davey 1988). The maximum egg production in B. microplus occurs at 25-30°C and its egg production seized below 10°C.…”

Prevalence of ixodid ticks in dairy animals of Jammu region

et al. 2013

View full text Add to dashboard Cite

To determine the prevalence of ticks, 960 bovines (cattle 480, buffaloes 480) were examined from organised and unorganised dairy units of Jammu district during March 2012 to February 2013. The overall infestation rate was found to be 42.18 %. The infestation rate in cattle was found to be 47.08 % while 37.29 % of examined buffaloes were infested with ixodid ticks. Among the ixodid ticks, only one species i.e. Rhipicephalus (Boophilus) microplus was recorded. A significantly (p < 0.05) higher prevalence was recorded in monsoon season as compared to other seasons. Agewise, the animals aged <6 months showed the highest prevalence and the lowest was found in animals >1 year of age. Sexwise, the males had higher infestation rate than the females.

“…Such an effect is predictable for any poikilotherm and has been reported for some ticks (Peirce, 1974;Ouhelli et al, 1982;Hussein and Mustafa, 1987;Guglielmone, 1992). However, in O turicata, the preoviposition, oviposition and egg incubation periods also are affected significantly by the RH and the interaction effect of the temperature and RH.…”

“…However, over a range of 45-95% RH, Sonenshine and Tigner (1969) observed no correlation between the preoviposition weights of female Amblyomma americanum and Dermacentor variabilis and the number of eggs they oviposited. Similarly, Sweatman (1968), Drummond and Whetstone (1970) and Ouhelli et al (1982) reported that the durations of the pre-oviposition and oviposition periods in Hyalomma aegyptium, Amblyomma maculatum and Boophilus annulatus are not dependent on the engorged weight of the female. This physiological difference underscores the fact that the impact of the environmental conditions on tick reproductive parameters is species specific.…”

“…Nearly all the ticks failed to oviposit at 22°C presumably because this temperature approximates the lower temperature tolerance of O. turicata for oviposition in its natural habitats. Some studies have demonstrated that temperature is the main environmental factor affecting the number of eggs oviposited by ticks (Sweatman, 1967;Sonenshine and Tigner, 1969;Ouhelli et al, 1982). However, in Boophilus microplus, the number of eggs oviposited is significantly reduced when the RH is below 40% (Bennett, 1974).…”

The effects of different temperatures and relative humidities (RHs) were tested on various reproductive parameters of Ornithodoros turicata, an argasid tick that inhabits gopher tortoise burrows in Florida, USA. The pre-oviposition, oviposition and incubation periods of the ticks decreased as temperature increased. These periods were also affected by the RH. The number of eggs oviposited was affected significantly by the combined effect of temperature and RH. Fewer eggs were laid by ticks in the 24 degrees C regimes and the 27 degrees C/95% RH regime compared to those in the other temperature/RH groups. There was an inverse relationship between the number of eggs oviposited and the percentage of hatched larvae that was correlated with the temperature and RH. Ticks reared at 27 degrees C/90% RH and 30 degrees C/90% RH laid more eggs than those reared in the other combinations of temperature and humidity but fewer larvae hatched from these eggs. The reproductive fitness index (RFI) values were highest in females held in the 24 degrees C groups and the 30 degrees C/95% RH group, although significantly more larvae hatched at the lower temperatures. The optimum reproductive conditions for O. turicata under laboratory conditions appear to be 24 degrees C and 90-95% RH. While mating occurred at all temperatures, none of the females laid eggs at 22 degrees C. The ticks may move preferentially to low temperatures when not feeding to remain above the critical equilibrium humidity and/or below the critical metabolic level necessary for prolonged survival. However, most female ticks oviposited after 45 days when moved to 27 degrees C/95% RH. Ornithodoros turicata females may have a limited capability to delay oviposition until an optimal microenvironment for egg deposition can be located in the burrow.
